Area forecast discussion, Jul 28, 6:15 PM CDT, 4 hours 6 minutes before
Area Forecast Discussion National Weather Service North Platte NE 615 PM CDT Sun Jul 28 2019 .SHORT TERM...(This evening through Monday night) Issued at 258 PM CDT Sun Jul 28 2019 Concern in the short term will be threat for thunderstorms later this evening across portions of north central Nebraska. Satellite analysis shows shortwave trough slowly pushing east of the area. At the surface, a cool front and associated wind shift line was currently stretching from just east of McCook to just west of O'Neill. Breezy northwest winds gusting to 25 mph at times will develop later this afternoon behind the boundary across the Sandhills, helping push in dry and cooler air. Ahead of the boundary, temperatures were still rising well into the upper 80s with dew points in the mid to upper 60s. SPC has elected to introduce a small Slight Risk for severe weather into far north central Nebraska counties, specifically Boyd and Holt Counties with a Marginal Risk for all other locations east of an Ainsworth to Broken Bow line. These storms should develop as trailing shortwave within the general northwest flow dives south- southeast through central South Dakota. Think the threat for any severe storms in the aforementioned areas to be limited as instability quickly diminishes through the evening and storms will be post-frontal and thus mostly elevated. Deep layer shear will be marginally supportive of multi-cell clusters but winds are weak in the lowest levels and the area will lack any significant low-level jet with modest DCAPE and delta theta-e values. The potential is there to see an isolated strong wind gust as storms gust out, but think most activity will remain below severe limits. Expect a cooler night tonight as the drier air, mostly clear skies, and light winds will allow for temperatures to fall into the 50s. Expect a mostly dry day on Monday as surface winds veer from north to southeast by late afternoon for portions of southwest Nebraska on the backside of departing high pressure further north and east. This will lead to the potential for thunderstorms during the evening as moist upslope flow develops within a narrow plume of moderate instability on the southern periphery of a modest h5 speed max. Conditions will be in place as daytime boundary layer mixing will erode any lingering capping inversion by late afternoon. Corfidi vectors and mean wind flow will help push any storms that develop over the higher elevations into portions of southwest Nebraska, specifically southwest of a Big Springs to Hayes Center line, during the evening. The SPC has painted a Marginal Risk for severe weather across that area given ample deep-layer shear. Limiting factor would be sharp west to east instability gradient but still believe an isolated strong wind gust with hail would be possible. Daytime highs on Monday will be cooler than seen recently, only topping into the upper 80s in the south to near 80 in the north. Rain and thunderstorm chances increase late into the evening as a stronger shortwave rounds the top of the developing ridge centered over New Mexico. Scattered rain and thunderstorms will continue through the overnight into early Tuesday, helping keep temperatures mild as lows remain in the 60s. .LONG TERM...(Tuesday through Sunday) Issued at 258 PM CDT Sun Jul 28 2019 Beginning 12z Tuesday. Overall weather pattern locally will revolve around the strengthening upper-level ridge expected to center over northern New Mexico and southern Colorado by mid-week. This will keep the area in general northwest flow aloft and prone to quick moving systems. Plenty of energy will move through the area during the work week leading to regular recurring rain and thunderstorm chances, favoring the evening hours as most development occurs over the higher plains and drifts east within the fairly uniform upper- level flow. Expect highest PoPs to be Tuesday night and Thursday night (aoa 40-50%) when lingering rain and thunderstorms from the west get local enhancement thanks to development of the nocturnal low-level jets that looks to nose into the area. Have trended temperatures warmer given increased agreement between global models on placement of ridging, but still slight differences remain regarding overall strength. Signs suggest ridging and thus northwest flow look to continue towards next weekend, leaving the area in a relatively active pattern with near daily, though limited spatially, rain chances. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 615 PM CDT Sun Jul 28 2019 Gusty northwest winds and isolated thunderstorms are the primary aviation weather concerns this evening. Surface winds will taper around sunset, but TSRA risk increases across far north central Neb (KONL) around 28/03z. VFR conditions are expected from Monday morning on. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...Jurgensen LONG TERM...Jurgensen AVIATION...Snively
